Description

Apparatus for cooling portable computer
The present invention relates to have the portable computer of PC card slots, relate in particular to the cooling device of portable computer.
The initial stage nineties, the quick growth of portable computing system promoted messaging device miniaturization, lightweight and portable aspect development.A soul-stirring innovation is exactly to develop the PC plug-in part technology.Because the effect of PC plug-in unit is big, highly versatile thereby make them become standardized component in many portable computers soon.PC plug-in part technology fast-developing and be received in by the whole world and should give the credit to international personal computer memory plug-in unit association (PCMCIA) to a great extent in the effort of having done aspect the standardization.
Nowadays the PC plug-in unit standard of PCMCIA is given various industry and rectilinear application (vertical application), and as chip card, top box (Set-top boxes), vehicle and other application have been brought the benefit of described PC plug-in unit.The PC plug-in part technology becomes the desirable technique of various applications with its compact size and durability.
Present PC plug-in unit standard code three types PC dongle configuration and additional expansion plugin structure.These three kinds of plug-in units all have identical length and width and adopt 68 needle connectors.Unique contour structures difference is exactly the thickness difference between the various plug-in units.The thickness of I type plug-in unit, II type plug-in unit and III type plug-in unit is respectively 3.3mm, 5.0mm and 10.5mm.Owing to be the thickness difference only, therefore relatively thinner plug-in unit can use on thicker groove, but thicker plug-in unit then can not use on relatively thinner groove.
Various types of plug-in units can both satisfy needs of different applications.I type PC plug-in unit generally is used to resemble the memory devices of RAM card, Flash card, OTP card and SRAM card and so on.II type plug-in unit is used for the I/O equipment such as data/facsimile modem, LANs and mass-memory unit.III type plug-in unit is used for the equipment of parts thicker (as rotary mass-memory unit).
Expansion card is convenient to those optional features that must be retained in the system outside, as the antenna operate as normal in wireless application field.
Version number refers to the kind of PC plug-in unit standard, and it is the working foundation of particular plug-in or system.In general, version 1.0 is only supported storer, and the 2.X version can support storer and I/O to use.
PCMCIA standard 1.0 versions/JEIDA4.0-1990 June
The first version of PCMCIA standard has defined the shape factor of 68 needle interfaces and I type PC plug-in unit and II type PC plug-in unit.The prototype version of PCMCIA standard has only been stipulated electric and structural requirement for memory card.It has defined intermediate form (Metaformat) or plugin information structure (CIS) for the PC plug-in unit, and this is extremely important to collaborative work between the PC plug-in unit and grafting-operation.In first version of PC plug-in unit standard, there is not I/O (I/O) card notion.
PCMCIA standard 2.0,2.01 and 2.1 versions-1991-1994
Second version of PCMICA standard is that 68 needle interfaces have defined the I/O interface, and this 68 needle interface is identical with 68 needle interfaces that are used for the PCMCIA memory card in the first version of standard.2.0 version has also increased various explanations on the basis of first version, to the support of two voltage memory cards and relevant requirement and chapters and sections such as method of testing to the plug-in unit environment for use.2.01 version has increased the ATA technical specification of PC plug-in unit and the type of III type plug-in unit, has also increased the technical specification of the automatic guiding mass storage (AIMS) that is suitable for digital picture.It also comprises the prototype version of plug-in unit maintenance instruction.2.1 version has further strengthened the maintenance instruction of plug-in unit and socket and has improved the plugin information structure.
PC plug-in unit standard--February nineteen ninety-five
The latest edition of PC plug-in unit standard has increased and has improved compatible information and increased some performances, as supports 3.3 volts of voltage power supplies, supports total line traffic control of DMA and 32 card buss of support.
The quick employing rate of PC card slots has promoted the stable tendency of plug-in unit and main frame.In the meantime, introduce the PC plug-in unit that contains new technology, in standard, increased the performance that new Special Significance is arranged.Meanwhile, the suppliers of plug-in unit, main frame and software have also obtained considerable experience, have recognized when this is the raising compatibility.
The target of PCMCIA is that this technology is used is convenient as far as possible.Yet this standard can only provide the guidance of some aspect, thereby always has some manufacturers can not follow this standard fully or this standard is had different understanding.Therefore, will consider maximum compatibility to dirigibility and adaptive improvement plan.A kind of method of preparing for various actual conditions is that the project organization with all particular components is carried out careful test from software function and assembly to whole worktable.
There are three kinds of principal elements to combine to have improved greatly the property coordinated with each other of PC plug-in unit.In the version in March nineteen ninety-five of this standard, in many aspects the software engineering specification of PC plug-in unit has been done improvement.Improvement to plugin information structure and guide for use thereof makes main frame be improved the recognition methods of plug-in unit performance and requirement.Some is to the replenishing of guide file in the version in March nineteen ninety-five, and they are for such as modulator-demodular unit, the criterion that the developer of specific type PC plug-in units such as wireless device, ATA card and card bus card recommends.
In addition, make property coordinated with each other be improved in the inner cooperation that increases between add-in developer, main frame developer and the software developer of industry.For this purpose, PCMCIA and P lug and Play association regularly co-host P lug Fest harmony study class, and the major vendor from the production each side has assembled in this study class.Expectation can more be improved.
Portable machine manufacturer and user still are faced with a lot of problems.Because many electronic equipments are encapsulated in the little cabinet, therefore a subject matter is generated heat exactly.For example, INTEL PENTIUM processor can produce excessive heat.Disc driver and other parts also can produce a large amount of heat.In the little cabinet such as laptop computer, these parts and miscellaneous equipment may overheated and finally break down portable computer.The overheated mean down time that also can shorten electronic unit.Therefore wish to have a kind of method that portable computer is cooled off be convenient to.
The present invention includes a kind of device that is used to cool off the electronic equipment that has the PC slot.This electronic equipment can be the equipment that contains PCMCIA type PC slot of portable computer or other type.According to the present invention, cooling device is put into the PC slot so that the guiding cooling air enters into the electronic equipment such as portable computer.
